I would need help with changing my regulatory domain for my wireless Alfa (AWUS036NHA) card (AR9271 chipset).
I haven't found any problems yet with the device except that I seem to not be able to change the regulatory domain for the card.
I'm running BT5r3 gnome on a bootable USB drive (not persistent).
I've seen the procedure work many times in videos etc..
If i monitor the kernel:
ifconfig wlan1 down
iw reg set [country code of your choice]
ifconfig wlan1 up
iw reg get (this should display your current country)
..and then plug in the wireless card this is what it says:
tail -f /var/log/messages
Then I type in (as expected):
Jan 10 22:32:37 bt kernel: [16775.708148] usb 1-2: new high-speed USB device number 14 using ehci_hcd
Jan 10 22:32:37 bt kernel: [16776.151244] usb 1-2: ath9k_htc: Transferred FW: htc_9271.fw, size: 51272

Jan 10 22:32:38 bt kernel: [16776.604405] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm)
And the kernel does not respond at all.
iw reg set [any two digit country code]
To check if it has changed:
It does not matter if I bring the card down first and up afterwards it is still at GB.
iw reg get
(2402 - 2482 @ 40), (N/A, 20)
When I activate the card with (ifconfig wlan1 up) regardless if it's before or after I've issued (iw reg set [XX]) the kernel says this:
(don't even know if that is helpful to know)
ADDRCONF(NETDEV_UP): wlan1: link is not ready
Am I missing any kind of updates or files I would need or is the problem more complex?
I'm a new user to both BT and linux but after many hours of searching I have to give up..
Is it just some stupid thing that I've missed or what is it?
If more info is needed just ask for it!
Take the chance to be my hero of the day!
